How to Grow Sage Indoors
Garden sage can be grown indoors year-round with proper care and maintenance. It is a perennial shrub with full, textured leaves and can grow to one to two feet in height.
Sage plants should be in direct sunlight. If it is kept in a windowsill, it should be rotated on a regular basis to prevent it from growing towards the light source. For optimal growth, sage should receive a minimum of six hours of sunlight per day.
Indoor sage plants should be watered when the top of the soil becomes dry. Sage does not respond well to overwatering and can develop root rot if watered too often.
Harvesting Indoor Sage
Harvesting should not be done until one year after planting. Sage leaves can be cut with scissors or pinched off with your fingers. A well-maintained sage plant will have a life span of two to three years. Cuttings can be taken from your original plant to cultivate new sage plants.
